Figure 1 - Gas chromatograms of volatile compounds collected from disturbed (up) and undisturbed (down) adults of Anchomenus dorsalis. 1 undecane 2 heneicosane 3 (Z)-9 - tricosene 4 tricosane. On the x axis is reported the retention time (minutes). As a stationary phase an HP5–MS capillary column was used. The GC oven temperature program was 60 °C for 5 min, than increased by 10 °C/min to 280 °C.
